Sri Lanka faces persistent dengue threat despite current case lull

Public health officials in Sri Lanka have cautioned against complacency over dengue fever, noting that a current decline in reported cases should not obscure the underlying risk of transmission across the island.

The warning comes as health authorities monitor epidemiological trends and vector activity. Officials stressed that mosquito breeding conditions remain favorable in many areas, particularly during the monsoon season, creating an environment conducive to disease spread.

Health department representatives have called for sustained public awareness campaigns and community participation in mosquito control efforts. Residents have been advised to eliminate standing water around homes, use insect repellent, and seek medical attention if symptoms appear.

The dengue virus, transmitted by Aedes mosquitoes, has historically affected Sri Lanka during certain seasons. Officials emphasize that low case numbers in any given period do not necessarily indicate reduced transmission risk, as cases can surge rapidly if preventive measures are relaxed.

Health authorities continue to encourage the public to maintain vigilance and cooperate with vector control programs, particularly in urban and semi-urban areas where mosquito populations tend to concentrate.
